Holy symbols can be made by having an unblessed symbol blessed by Brother Jered in the monastery west of Edgeville, or by blessing it yourself by using a holy book or book of balance on an unblessed symbol at 50 Prayer, requiring a few prayer points. Blessing by Jered requires at least 31 Prayer. They have the second highest prayer bonus for an amulet in game (after the god stoles). They aren't expensive/hard to obtain, therefore are commonly used in conjunction with Proselyte armour and other high prayer granting armour when using protect prayers as a form of defence when training.
